1. 12/2= 6 (6 minutes per kilometer)
2. 10000/1000= 10 (10000m is 10km)
3. 10*6= 60min
If this helped, please consider picking this answer as the Brainliest Answer. Thank you!
Answer:
60 minutes or 1 hour
Step-by-step explanation:
Time taken to cover the distance of 2 km = 12 minutes
10000m = 10km
Then time taken to cover the distance of 10 km = 5 x 12 = 60 minutes
I have multiplied 12 with 5 because if we multiply 2km with 5 we will get 10km. So, hope you understood my explanation. If not ask me your doubt in comment.

Step-by-step explanation:
percentage change value formula
c2 = X2 - X 1 X 100
X1 1
WHERE,
C2 = RELATIVE VALUE
X2 = FINAL VALUE ( TODAY'S VALUE) = 32,860
X1 = INITIAL VALUE (1992 VALUE) = 15,500

Answer:
c.14
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
To get the Greates Common Factor (GCF) of 238 and 462 we need to factor each value first and then we choose all the copies of factors and multiply them:
238: 2 7
462: 2 3 7
GCF: 2 7
The Greates Common Factor (GCF) is: 2 x 7 = 14
A pen costs twice as much as a pencil. If 7 pens and 12 pencils cost $6.50, find the cost of a pencil.
I know the answer (pencil $0.25, pen $0.5), but I need to figure out how the answer is solved.
1. Observe the problem
2. Make a system of linear equations
x is pens
y is pencil
As stated in the text, x=2y
x=2y

Find the cost of leveling a badminton court 132m long and 58 m broad at the rate of Rs. 80 per sq. m.
Answer:
Rs. 612,480
Step-by-step explanation:
Hi there,
Here the question asks us to find the cost of leveling a badminton court at the rate of Rs.80 per sq..
So by the word leveling we know that we have to find the area of the court in order to proceed further.
(I am assuming the court to be rectangular in shape).
Area of a rectangle = Length * Breadth
*Length = 132 meters
*Breadth = 58 meters
==> 132*58= 7656 m^2
So now that we got the area of the badminton court lets find the cost of leveling it ==>
Cost of leveling per meter^2 = Rs. 80
Area = 7656 m^2
==> 7656 * 80 = 612,480
So the cost would be Rs. 612,480

Big Red Gymnastics Academy charges an initial fee of $ 200 to rent its gym for birthday parties. The academy then charges an additional $75 per hour. Write an equation that gives the total cost of the gym as a function of gym time (in hours).
A. y= 75x - 200
B. y= 200x + 75
C. y= 75x + 200
D. y= 200 - 75x
Answer: C. y= 75x + 200
Step-by-step explanation:
Since they charge $75 an hour x represents the house and they charge an initial fee of $200 so you add that to the $75 an hour
Answer:
C
Step-by-step explanation:
The equation y = mx + b helps use to solve this type of problem
We know the initial amount to rent the gym is $200, that will be our b for this case since it is the y-intercept. This is the y-intercept since that is the initial amount.
The slope for this equation will be 200 represented by m. The key term that represents this is out slope is per. "$75 per hour." Since the function is in hours we don't need to convert hours into another unit.
Now if we plug in the variables, we get the equation y = 75x + 200 which is what C is.

Answer:
D. 8-cm square
Step-by-step explanation:
The smaller square shown on the figure has an area of 15×15 = 225. The sum of the two smaller square areas must equal the larger square area, so the smallest square must have an area of ...
289 -225 = 64
